Then catch a box full of Dittos and check their IVs. Start breeding your mon until at least the two IVs of the Ditto pass down, then switch out with a different Ditto with different IVs.
At one point, you will get a male and a female of your mons that complement each others IVs and that's when you should breed them for higher rates.
